Examination in case of suspected cardiac arrhythmias begins with the analysis of complaints, collection of medical history, and assessment of the general condition of the patient. The doctor clarifies how often the symptoms occur, what provokes them, and whether they affect well-being and daily activity.
The main diagnostic method is an electrocardiogram, which allows recording rhythm disturbances and assessing the work of the heart at the time of the examination. However, many arrhythmias are periodic in nature and may not manifest themselves during a short recording.
In such cases, additional methods are used:
- 24-hour ECG monitoring (Holter monitoring) — allows assessing the work of the heart over 24–48 hours and recording episodes of rhythm disturbance under different conditions;
- ultrasound of the heart — is used to assess the structure of the myocardium, the function of the heart, and to detect concomitant changes;
- laboratory tests — help identify hormonal or metabolic disorders that may affect the heart rhythm.
After establishing the diagnosis, the doctor determines the management tactics for the patient. It depends on the type of arrhythmia, the frequency of episodes, the severity of symptoms, and the presence of concomitant diseases.
In some cases, observation is sufficient, however, active treatment of arrhythmia is necessary if:
- the symptoms affect daily life (weakness, dizziness, irregularities in the work of the heart);
- the episodes occur frequently or tend to progress;
- there is a risk of complications, in particular thrombus formation or heart failure;
- rhythm disturbances are associated with heart diseases or other systemic disorders.
Most arrhythmias do not require complex interventions and are well controlled by conservative methods.
The main approaches to treatment include:
- drug therapy — the use of medications to normalize the heart rhythm or control the heart rate;
- heart rhythm control — individually selected therapy aimed at reducing the frequency of episodes and improving well-being;
- catheter treatment methods (radiofrequency ablation) — are used less often, mainly in persistent or symptomatic rhythm disturbances, when drug therapy is not sufficiently effective;
- implantation of a pacemaker — is used in cases when the heart cannot maintain a sufficient rate of contractions on its own.
Treatment tactics are selected individually and depend on the type of arrhythmia, the frequency of its occurrence, the presence of symptoms, and the general condition of the cardiovascular system. An important role is also played by the prevention of arrhythmia, which includes control of risk factors, correction of lifestyle, reduction of stress level, and timely treatment of concomitant diseases.
